Definitions

• ABSTRACT Hair shapingfcomposition comprising a mereapto salt of a carboxylic acid together with a salt of ascorbic or glyoxylic acid; The permanency of the shaping and elasticity of the hair are improved.
• This invention relates to a permanent wave composition and more generally to a'hair-shaping composition for human hair and a process of using it.
• the shaping of human hair ordinarily is carried out by applying a reducing agent to the hair. This results in an opening up of the bridge connection between the peptide chains in thekeratin of the hair due to reductive action and thus causes a softening of'the hair. If a permanent wave is wanted the hair is then brought into the new shape by means of rollers. If a permanent straightening of curly hair is desired the shaping is effected by combing the softened hair. After the agent has acted on the hair for a sufficient time, for instance between and 20 minutes, the excess shaping agent is usually rinsed off with water and the hair is then treated with a suitable oxidizing setting agent. This after-treatment causes, within the necessary period of time, such as 10 to minutes, an oxidative recrosslinking of the broken bridge connections. The hair thus is permanently set in the new shape.
• Suitable reducing agent used in these processes are principally salts, preferably ammonium salt, of mercapto carboxylic acids preferably of'thioglycolic acid and thiolactic acid.
• the subsequent setting of the hair' is preferably effected with hydrogen peroxide or its addition compounds as oxidizing agent. It is thus possible to obtain permanent waving or permanent straightening of the hair which usually lasts for a few months.
• these processes havevarious shortcomings because of too little shaping which also starts partly disappearing soon and because of lack of elasticity of the hair.
• the present invention resides in the finding that these shortcomings can be avoided by adding to the shaping composition which, as customary consists of a salt of a mercapto carboxylic acid, additionally a salt of ascorbic or glyoxylic acid.
• the shaping composition is applied to the hair and permitted to become effective whereupon thereafter a setting composition containing hydrogen peroxide or an addition compound thereof is applied.
• the setting agent may be applied to the hair after application of the shaping composition without intermediate rinsing.
• the purpose of the treatment is to obtain a permanent wave for the hair it is preferable to pre-wet the hair with a portion, such as about one-half to two-thirds of the shaping composition and then to roll up the hair on the permanent wave rollers.
• the rolled up hair is then further wetted with the remainder of the shaping composition and may be shielded by means of a hoodshaped plastic cover.
• the rolled up hair is then treated with a portion, such as about one half of the setting composition which is permitted to act on the hair for about 2 to 3 minutes.
• the hair is then unrolled from the rollers and thereafter the remainder of the setting agent is applied which is again permitted to act on the hair for another 1 to 3 minutes.
• the hair is finally rinsed with water which step may be followed by the usual final treatment for obtaining the desired hair style.
• the shaping agent in a thickened form is applied to the hair and is permitted to act on it forabout 10 to 20 minutes while the hair is repeatedly combed.
• the hair is subsequently treated for about 3 to 7 minutes with a setting agent which likewise is used in thickened condition. This is followed by rinsing of the hair with water. Thereafter the usual final treatment may be carried out for obtaining the desired hair style.
• Both of the desired processes are paricularly suitable embodiments for obtaining a permanent shaping of the hair.
• the invention is not limited thereto.
• a somewhat longer or shorter treatment time may be advantageous.
• a shortening of the time for shaping the hair may also be effected by additionalextemal application of heat such as by a drying hood while the shaping agent acts on the hair.
• the process of the invention can also be carried out in other known manners but an intermediate rinsing between the shaping step and setting step should be omitted.
• an intermediate rinsing between the shaping step and setting step should be omitted.
• the pro-wetting of the unrolled hair with the shaping composition can be omitted.
• the washed and towel dry hair in this case is treated with the shaping composition only after rolling up the hair on the rollers.
• the oxidizing substance contained in the setting agent is present in an amount to have always present an excess relative to the reducing agents in the shaping composition.
• the salts of the ascorbic and/or glyoxylic acid are preferably employed in a total concentration of about 2 to 4%.
• the salts may be the water soluble ammonium-, alkali-, or earth alkali salts and preferably are selected from the group consisting of ammonium, lithium, sodium, potassium and magnesium salts. It should be understood however that these salts neither by themselves have a hair shaping effect nor do they have a activating effect on the effective agents present in the mercapto carboxylic acid salts.
• the remaining parts of the shaping agent may be as conventional. They may contain the water soluble salts of mercapto carboxylic acids, such as the ammonium or alkali salts, for instance sodium or potassium salts of thioglycolic or thiolactic acid in a concentration of about 0.2 to 1.2 mol per liter.
• the composition should be used in an alkaline condition preferably at a pH between 7 and 9.6.
• the shaping composition is preferably used in the form of a solution or liquid emulsion.
• the hair thickened compositions in the form of creams or gels are preferred.
• the setting agent used in combination with the shaping agent of the invention is based, as conventional on hydrogen peroxide or its addition compounds.
• addition compounds may for instance be mentioned urea peroxide, melamine peroxide and sodium perborate.
• the solutions preferably are neutral or acidic aqueous solutions containing about 2 to 4% hydrogen peroxide.
• the usual additives such as wetting agents, perfuming oils, dyes, dulling agents, thickeners, fats, waxes and similar.
• A. Permanent wave solution 10.0 g ammoniumthioglycolate 3.7 g ammonium salt of glyoxylic acid l.0 g ammonia (as NH 0.3 g perfuming oil 0.3 g castor oil 40 mol of ethylene oxide Balance water The solution has a pH of 9.2 and 21 contents of thioglycolic acid of 6.6%.
• the hair was per-wetted with 50 g of the above-listed permanent wave solution and was then rolled up on permanent wave rollers. The hair in rolled up condition was then premeated with the balance (50 g) of the permanent wave solution. In an alternative embodiment it was shielded with a hood-shaped plastic cover.
• the rollers were removed and the hair was treated with the remainder (50 g) of the setting lotion. The latter was left on the hair for another I to 3 minutes. The hair was then rinsed with water and finally treated in customary manner to obtain the desired style.

• magnesium salt of glyoxylic acid was used instead of the 0.6 g of ammonium salt of the same acid.
• the hair was repeatedly combed.
• the straightening effect occurred after a time of about minutes.
• the setting cream was then applied and spread with a comb. After a period of about 5 minutes the straightened hair was rinsed with water and then treated in conventional form to obtain the desired hair style.
